PHP Regex....

Mmm. I've been having a weird problem with this regex!

I'm using preg_match, which should just match a string.

I'm using;

Code:
if (!preg_match("/^[0-9a-zA-Z_.-]*@[0-9A-Za-z_.].[a-zA-Z]{2,4}/",$email)) { error("Email address $email does not seem to be valied!"); }

However, if I add a - in, as such;

Code:
if (!preg_match("/^[0-9a-zA-Z_.-]@[0-9A-Za-z_.-].[a-zA-Z]{2,4}/",$email)) { error("Email address $email does not seem to be valied!"); }

If I escape it with a \, it still doesn't match!

It will match all of these combinations WITH the - there, just not escaped;

my-webmaster@ewee.com
webmaster@mydomain.com
webmast@something.ws
some-thing@somewhere.co.uk

Ones that don't work;

my-webmaster@ewe-oioe.com
someone@my-domain.com
and anything with an - after the @ sign!

Anyone had experience with this regex before, and if so, any ideas why its doing that? Unimpressed

Thanks

Your top and bottom regexs aren't the same. The second one has a possible problem which is [b]

Try this:

!preg_match("/^\S+@\S+\.\S+/",$email)

Im not sure if regex works the same in php but if so then above should work.

Argh...that shouldn't have come out like that! For some reason it has made [b]-[/ b] come out as [ b.]- Unimpressed

Possibly a bug (I tried to edit it..but for some reason no matter how i edit it I can't get it to come up bold!).

So, its not that [b.] part that is wrong with the code Wink
